How do I fix corrupted BIOS? tx2500

[rampingray]

My tx2500 gives the double LED flash that signals it has a corrupted BIOS.  According to this URL you can "restore BIOS from onboard backup (jumpers)."  If anybody has an idea what this means and how to fix my computer I would be very thankful.

Here are two possible methods to restore that BIOS:

=====================================================================================

Option:  see if your system can Restore the BIOS:

Select your Notebook from this List of tx2500 Series

Go to:

Solve a Problem > Memory (RAM) / Motherboards / BIOS > BIOS / UEFI > Restoring the BIOS

For example, if the HP Pavilion tx2500 CTO is your notebook, then this is your Page:  Restoring the BIOS

---------------------------------------------------------------------------------------------------------------------------------------

Option - Use the UEFI environment to Restore the BIOS

• From a Complete shut down condition (all off),
• Press the power button and
• Immediately tap the ESC key to get into the "Start Menu"
• Select "F2" to start the HP Advanced Systems Diagnostics menu screen
• Select BIOS / Firmware Management

--------------------------------------------------------------------------------------------------------------------------------------

Option - Download the BIOS file from your notebook's own webpage -- Software and Downloads section

• Extract the contents and put the files onto the root of a USB thumbdrive
• Connect the thumbdrive to a USB 2.0 port on your system
• Connect the AC power adapter.
• From a complete shut down condition (all off),
• Press the power button and
• Immediately hold the Windows key while tapping on the "B" key
• The BIOS update process should start
• Follow the prompts to restore your BIOS, using the BIOS file on your thumbdrive

Thanks for the reply, but neither of these worked. The computer beeps, but the screen stays black and the LEDs keep flashing

The root cause of the problem is not necessarily the BIOS.

The number of beeps and flashes is usually indicative of the underlying issue; in some cases the problem is admittedly more difficult to track down.

I fixed the BIOS problem by taking out half of the RAM. Now the computer partially boots windows and the screen freezes which I have read is a permanent problem.
